The original code used that.beanName to access the private field beanName, which is not allowed. Changed to use getter method.

Hi @Alioth4J,

Congratulations on submitting your first PR for the Spring Framework! 👍

Unfortunately, your analysis is incorrect: in Java it is permissible to access a private field of an instance of the same type within methods of that type.

In light of that, I am closing this PR.

Regards,

Sam
